Polymorphic microsatellites in a mangrove species, Rhizophora mangle L. (Rhizophoraceae) uri icon

abstract

  • Twenty-six microsatellite loci were isolated and characterized from the mangrove species Rhizophora mangle using (GT)(n) and (CT)(n) repeats. Eighty-four percent of the clones contained microsatellite sequences; the most common dinucleotides were the (GA/CT) and (CA/GT) repeats. Ten primers were selected to investigate the polymorphism among individuals of R. mangle from two natural populations of the Colombian Pacific Coast. The observed heterozygosity per locus varied from 0.20 to 0.80, the power of discrimination was 0.32-0.84 and the power of exclusion was 0.03-0.75. This set of microsatellites offers an efficient tool for population genetics studies on this species.
